If that were the case, why doesn’t someone just produce the audit and be done with it?

Where are the records of these audits?

Where are the records of these audits?

Here you go:

Federal Reserve System Audited Annual Financial Statements

Want to know what securities they've bought? Look here:

System Open Market Account Holdings of Domestic Securities

There's a lot more information available about their operations.

Is there something in particular you want to see from an "audit" that isn't already out there?
